I really do not think that TARGET_REMOTE_ADDR_BIT should be
necessary... in what way was TARGET_ADDR_BIT/TARGET_POINTER_BIT
inadequate? Do you have different sized code and data pointers?
Oh, reading further down the patch I see that AVR is a Harvard
architecture. There is support for this in GDB, with
CODE_SPACE/DATA_SPACE that were recently introduced (for the d10v, I
think). You may have some problems if they are of different size, I
suppose.
Also, I think (.avrgdbinit aside...) that you should not have a
tm-avr.h at all. You can set multi-arch from configure.tgt.
